- IMPROVEMENT lN RAISING AND TRANSFERRING HIDES IN TAN-VATS.

Specication forming part of Letters Patent No. 219.537. dated September9, 1879; application filed July 12, 1879.

To all whom it may concem:

Be it known that I, JosEPH ALEXANDER SMITH, of Rochester, in the countyof Monroe and State of New York, have invented a new and usefulInprovementin Machines for Raising, Floating, and Transferring Hides inTan- Vats, of which the following is a specification.

Figure 1 is a top View of my improved machine. Fig. 2 is a verticallongitudinal section of the same, taken through the lnew x, Fig. 1.

The object of this invention is to improve the Construction of themachine for which Letters Patent Nos. 205,:396 and 214220 were grantedJuly 2, 1878,`anfd April 8, 1879, so as to fnrnish an improved machinefor use in tanneries, for raising and floating hides in tanvats, and fortransterring them from one vat to another, which shall be simple inConstruction and convenient in use.

The invention consists in the combination ot' the two sets ot' shafts,gear -wheels and cranks, and the four cords with the frame and the rackthat receives the hides; and in the combina-tion ot' the detachable sideracks with the rack that receives the hides, as hereinafter fullydescribed.

Similar letters of reference indicate coresponding parts.

A represents two tan-vats. B represents the frame to which the Operatingm echanism is applied.

To the lower ends of the legs ot' the frame B are pivoted flanged wheels(J, to roll along the edges of the vats, or upon rails laid along theedgcs ot' the vats, and crossing the alleys between the vats.

To the frame B are pivoted pawls I, which engage with the shafts D, tohold them in place in either position.

The two shaft-s H -evolve in bearngs attached to the fra-me B, and toeach of them are attached two pins, h', to receive the loops formed uponthe npper ends of the four cords J.

The lower ends of the cords J are attached to the four corners of therectangular rack or frame K, upon which the hides are placed.

With ths constrnction, by tnrning the two cranks E equally, the fourcords J will be wound up eqnally, and the rack K and the hides placedupon it will be raised evenly, so that the hides will not be liable tofall ofi' as the machineis being moved from one vat to another.

The rack and its contents are held in place When raised by the pawls L,which are pivoted to the frane B, and eng-age with the teeth of thegear-wheels G.

In the outer bars ot' the rack K are formed holes, or to them areattached sockets or keepe's, to receive the lower ends of the side racksor frames, M, which racks M are designed for use when transferrin ggreen hides to keep them from slipping oti' the said rack K, and whichmaybe 'eadily detached when not required for use.

The side racks, M, may be connected at their corners by hooks to preventthem from being pressed outward.

Having thus fully described my invention, I claimas new and desire tosecure by Letters Patent I 1. The combination of the two sets of shaftsD H, gear-wheels F G and cranks E, and the four cords J with the fra-meB and the rack K, that receives the hides, snbstantially as herein shownand described.

2. The combination of the detachable side racks, M, with the rack K,that reeeives the hides, snbstantially as herein shown and described.

JOSEPH ALEXANDER SMITH.
